It is Mother Earth’s month, the 50th Anniversary of Earth Day… and a great time to announce that our Marketing Content Calendar is now LIVE online!

At the end of 2017, we released our 2018 Marketing Content Calendar in a PDF and hard copy format with over 400 #HashtagHolidays. With feedback from the initial release, we decided an online version would make it easier for local business, non-profit organizations and our online community to get relevant dates for their marketing strategy.

Our online calendar lists almost 500 international and national holidays, and business and environmental observances across the world. Dates shown are up to July 2020. Each month we plan to release an extra month i.e., August 2020 dates will show up by first week of July.

Plan your Marketing with Sustainability Content

Knowing about relevant holidays and observances can help you build a better digital marketing strategy, especially a marketing content plan, and to integrate sustainability into your activities – business or personal.

  • Learn topic ideas to create or curate content, or develop a campaign.
  • Consider events to get involved with as a volunteer or organizer.
  • Demonstrate your commitment to your customers experience and sustainability.
  • Plan out donations throughout the year.

Moreover, you can determine themes to consider and best times to promote to your audience. Think of how can you work each day into a conversation, and in what way does it apply to your customers.
